Why is my LG STYLO from Metro PCS keep shutting down??? PLEASE HELP THIS IS SO ANNOYING!!

Almost daily sometimes a few times a day all of a sudden my phone will have a blue ball roll across the screen & freeze. I then need to take the battery out put it back in & wait what seems like forever for all my apps to load back up. Even them most times it still doesn't work & I need to repeat the process 4-5 times. Metro will not replace my phone work a new one & it's been going on since the 1st hour of purchasing the phone. I just don't know what is wrong or what to even do at this point. Any suggestions that can help will be greatly appreciated
